Breastfeeding Practices among Postpartum Women with and without a History of Gestational Diabetes Mellitus: A Prospective Study

Objective: To compare breastfeeding (BF) practices, particularly exclusive BF (EBF), among women with and without a history of gestational diabetes mellitus (GDM) during the first six postpartum months and assess the impact of EBF on offspring weight from birth to six months postpartum. Materials and Methods: The present study was a prospective study that included 244 women, with 123 with a history of GDM (GDM group) and 121 without a history of GDM (non-GDM group). All participants were first interviewed on the discharge date and then via telephone at 1, 2, 3, 4, 5, and 6 months postpartum. BF practices were classified as EBF, partial BF (PBF), or no BF. Data on infant weight at six months were evaluated. Results: Upon hospital discharge, women mostly practiced PBF with 53.6% PBF versus 30.1% EBF in the GDM group and 48.8% PBF versus 38.0% EBF in the non-GDM group. However, EBF was more commonly practiced than PBF, during the first six months postpartum. The 6-month EBF rates for the GDM and non-GDM groups were 28.4% and 17.4%, respectively (p=0.039). In a multivariate analysis, only the intended EBF period was a factor that significantly impacted 6-month EBF rates (adjusted odds ratio 3.49 and 95% confidence interval 1.48 to 8.22). EBF for six months resulted in reduced weight gain during the first six months of life among offspring of women in both groups. Conclusion: The GDM group practiced EBF for six months postpartum more frequently than the non-GDM group. However, a history of GDM was not an independent predictor of EBF success over six months. EBF demonstrated lower offspring weight gain from birth to six months postpartum for women with and without a history of GDM. These findings may be used to design targeted educational programs for informed postpartum BF practices.

Partner relationship quality and IL-6:IL-10 trajectories from pregnancy to a year after-birth

BackgroundInflammatory activity during pregnancy and the postpartum period shifts systematically due to pregnancy progression, delivery, and postpartum recovery. Factors that deregulate inflammatory activity increase the risk for adverse pregnancy outcomes and slower postpartum recovery. The IL-6:IL-10 or TNF-α:IL-10 ratio is potentially one way to capture peripheral inflammatory regulation; higher values indicate that anti-inflammatory IL-10 is less effective at regulating pro-inflammatory TNF-α or IL-6, skewing towards maladaptive pro-inflammatory profiles. Associations between partner relationship quality and IL-6:IL-10 or TNF-α:IL-10 trajectories during pregnancy and the postpartum period have not been assessed. The purpose of this study was to test whether partner relationship quality (support, conflict) is associated with attenuated IL-6, IL-10, TNF-α, TNF-α:IL-10 or IL-6:IL-10 trajectories from the third trimester to the postpartum period. MethodsA sample of 162 women from the Healthy Babies Before Birth study reported on partner relationship quality (support and conflict) using the Social Support Effectiveness Questionnaire during the third trimester. Plasma samples were collected in the third trimester and at 1-, 6- and 12-months postpartum, and assayed for TNF-α, IL-6 and IL-10. Associations between both indicators of relationship quality (support and conflict) and TNF-α, IL-6, IL-10, IL-6:IL-10, TNF-α:IL-10 trajectories were tested using multi-level modelling, controlling for sociodemographic, pregnancy and health variables. ResultsPartner support interacted with time to predict IL-6:IL-10 trajectories, linear: b = -0.176, SE = 0.067, p =.010, quadratic: b = 0.012, SE = 0.005, p =.009. Lower partner support was associated with steeper increases in IL-6:IL-10 from the third trimester to 6 months postpartum, followed by steeper decreases in IL-6:IL-10 from 6 months postpartum to a year after birth. Partner conflict was not associated with IL-6:IL-10 levels at study entry, b = 0.233, SE = 0.219, p =.290, or over time, p’s > 0.782. Neither indicator of partner relationship quality was associated with TNF-α, IL-6, IL-10, or TNF-α:IL-10 trajectories, p’s > 0.205. ConclusionLower partner support may be associated with reduced moderation of IL-6 by IL-10 between pregnancy and a year postpartum, with possible consequences for maternal health and well-being.

COVID-19 pandemic-related trauma symptoms are associated with postpartum alcohol consumption

ObjectiveThe COVID-19 pandemic has led to escalations in substance use, including alcohol consumption. Of particular concern are the potential impacts during the postpartum period, a time of heightened vulnerability to stress and potential transmission of the negative sequelae of substance use to offspring. However, postpartum alcohol consumption during the COVID-19 pandemic has not been well characterized. MethodPostpartum drinking habits and COVID-19-related stress were repeatedly assessed (every two weeks for 12 weeks, and at one-, six-, and 12-months postpartum) from N = 378 individuals during the COVID-19 pandemic. Average alcohol use trajectories as well as heterogeneity in trajectories were characterized. COVID-19-related trauma symptoms and coping were examined in relation to alcohol use over time. ResultsAverage postpartum alcohol use included an initial quadratic increase from one-to-four-months postpartum, followed by a plateau between four-to-12-months. Higher (15.08%), moderate (26.90%), and lower consumption (57.90%) subgroups were identified. Endorsement of COVID-19-related trauma symptoms and using alcohol to cope with stress predicted higher consumption. ConclusionsFindings suggest a potential sensitive period in establishing postpartum alcohol use patterns from one-to-four-months postpartum. Findings further suggest that postpartum alcohol use is heterogenous and that individual response to major traumatic stressors, like the COVID-19 pandemic, may influence emerging patterns of postpartum alcohol use.

Exploring the role of inflammatory parameters in predicting isthmocele formation following planned cesarean section: a study in patients with a history of one previous cesarean

Objectives: Isthmocele is a hypoechoic area within the lower uterine segment myometrium, resulting from a discontinuation of the myometrium at the site of a previous cesarean scar. The aim of this study was to examine the influence of maternal cellular and inflammatory status prior to Cesarean Section (CS) on isthmocele formation. Methods: This prospective observational study was conducted in a tertiary hospital and included women with a history of one previous CS. The inflammatory and cellular parameters were collected and ultrasonographic examinations were conducted in the 6th postpartum month and then analyzed. Logistic regression analysis was performed to identify potential factors influencing isthmocele formation. Results: Of the 106 patients, 31 (29.2%) were diagnosed with isthmocele after one previous CS. There were no significant differences in terms of demographical variables between the groups. However, the duration of CS was significantly longer in the isthmocele group compared to the group without isthmocele (42.58 ± 8.77 vs. 38.42 ± 9.50 minutes, p = 0.03). The neutrophil-to-lymphocyte ratio (NLR) was higher and platelet-to-lymphocyte ratio (PLR) was lower in the isthmocele group (p < 0.001). Logistic regression analysis revealed that, NLR (OR [odds ratio]: 0.23, 95% CI [confidence interval]: 0.117- 0.473, p < 0.001) and PLR (OR: 1.05, 95% CI: 1.027-1.078, p < 0.001) were identified as independent predictors for isthmocele formation after planned CS. Conclusion: Inflammatory markers, such as NLR and PLR, may contribute to the formation of isthmocele in women with a history of one previous CS, shedding light on the underlying pathophysiology.

Long-Term Maternal and Child Outcomes Following Postnatal SSRI Treatment

Although selective serotonin reuptake inhibitors (SSRIs) are recommended for postnatal depression treatment, there is a lack of evidence regarding long-term maternal and child outcomes following postnatal SSRI treatment. To examine whether postnatal SSRI treatment moderated postnatal depression-associated maternal and child outcomes across early childhood years. This cohort study used longitudinal data from the Norwegian Mother, Father and Child Cohort Study. Participating women were recruited in weeks 17 to 18 of pregnancy from 1999 to 2008 and were prospectively followed up after childbirth. Data analysis was performed between December 2021 to October 2022. Postnatal depression diagnosis (a binary indicator of eligibility for treatment) was defined as a score of 7 or greater on the 6-item version of the Edinburgh Postnatal Depression Scale. The Hopkins Symptom Checklist was used as a continuous indicator of and postnatal depressive symptomology at postpartum month 6. Postnatal SSRI treatment was identified using self-reported data at postpartum month 6. Maternal outcomes included self-reported depression symptomology and relationship satisfaction from childbirth to postpartum year 5. Child outcomes included maternal-report internalizing and externalizing problems, attention-deficit/hyperactivity disorder symptoms, and motor and language development at ages 1.5, 3, and 5 years. A propensity score adjustment method was used to control for prenatal factors associated with postnatal SSRI exposure probability. Among a total of 61 081 mother-child dyads, 8671 (14.2%) (mean [SD] age, 29.93 [4.76] years) met the criteria for postnatal depression diagnosis, 177 (2.0%) (mean [SD] age, 30.20 [5.01] years) of whom received postnatal SSRI treatment. More severe postnatal depression symptomology was associated with a range of adverse maternal and child outcomes. Focusing analyses only on the postnatal depression dyads indicated that postnatal SSRI treatment attenuated negative associations between postnatal depression and maternal relationship satisfaction at postpartum month 6 (moderation β, 0.13; 95% CI, 0.07-0.19), years 1.5 (moderation β, 0.11; 95% CI, 0.05-0.18) and 3 (moderation β, 0.12; 95% CI, 0.04-0.19), and for child ADHD at age 5 years (moderation β, -0.15; 95% CI, -0.24 to -0.05). Postnatal SSRI treatment mitigated the negative associations between postnatal depression and maternal depression, partner relationship satisfaction, child externalizing problems, and attention-deficit/hyperactivity disorder up to 5 years after childbirth. The results of this large prospective cohort study suggest that postnatal SSRI treatment was associated with a reduced risk of postnatal depression-associated maternal mental health problems and child externalizing behaviors across early childhood years. These findings suggest that postnatal SSRI treatment may bring benefits in the long term to women with postnatal depression and their offspring. This study potentially provides valuable information for clinicians and women with postnatal depression to make informed treatment decisions.

Sleep-wake timing and chronotype in perinatal periods: longitudinal changes and associations with insomnia symptoms, sleep-related impairment, and mood from pregnancy to 2 years postpartum.

Across the perinatal transition, existing research focuses mainly on significant changes in sleep duration and quality, neglecting sleep timing. This study investigated change trajectories of sleep timing and chronotype from late pregnancy to 2 years postpartum and examined longitudinal associations of chronotype with symptoms of insomnia, daytime sleep-related impairment, and mood. Data were from a two-arm randomised controlled trial testing parent-focused wellbeing interventions. Participants were a community sample of nullipara without severe sleep/mental health conditions. Participants self-reported bedtime, rise-time, chronotype, insomnia symptoms, sleep-related impairment, depression, and anxiety at seven time points: gestation Weeks 30 and 35, and postpartum Months 1.5, 3, 6, 12 and 24. Trajectories were estimated using mixed-effects models with continuous time, quadratic splines, and a knot at childbirth, controlling for age and group allocation. A total of 163 participants (mean [SD] age 33.35 [3.42] years) took part. Bedtime and rise-times delayed during late pregnancy (~8 and ~20 min, respectively) but became progressively earlier (~20 and ~60 min, respectively) over the 2 postpartum years. Chronotype became more eveningness in late pregnancy, and more morningness after childbirth, however changes were small. Controlling for sleep duration and efficiency, greater morningness was associated with significantly less symptoms of insomnia and sleep-related impairment over time (all p < 0.001); longitudinal associations between chronotype and symptoms of depression and anxiety were non-significant (all p > 0.65). Sleep-wake timing and chronotype became progressively earlier from pregnancy to 2 years postpartum. Morningness chronotype may be sleep-protective during the transition from pregnancy to parenthood. Mechanisms underlying these associations require further research.

Maternity care experiences and breastfeeding at discharge among Maryland WIC participants: A qualitative analysis.

Breastfeeding imparts numerous health and social benefits for families. Barriers deter some individuals from breastfeeding. Rates are lower among certain populations, including participants of the federally funded Women, Infants, and Children's Program (WIC). Women, Infants, and Children's Program provides low-income pregnant and postpartum women and children under 5 with nutrition education, supplemental foods, breastfeeding education and support, and resource linkages. Investigation of WIC participants' hospital experiences and breastfeeding decisions is limited. We explore qualitative themes associated with breastfeeding-related hospital maternity care practices experienced by WIC participants. Thirty pregnant individuals intending to breastfeed were recruited at WIC clinics to complete in-depth interviews at 2 weeks, 3 months, and 6 months of postpartum. Using the Thematic Framework methodology, we analyzed data from the two-week interviews of 29 participants with respect to hospital breastfeeding experiences. Fourteen participants were exclusively breastfeeding at discharge (EBFD). Fifteen were partially breastfeeding at discharge (PBFD). Differences between groups were found in hospital breastfeeding experiences, particularly in staff support. All participants EBFD reported positive breastfeeding-related staff experiences. Most participants PBFD reported limited and ineffective staff interaction, leading to formula introduction. Individuals EBFD and those PBFD reported about the same rate of hospital breastfeeding difficulties, yet half introduced formula within the first few days postpartum. Results reiterate the importance of hospital staff support to breastfeeding exclusivity at 2-3 days postpartum. The challenges that these individuals faced may have been resolved through available, responsive, and effective intervention. Data-driven breastfeeding education programs for hospital health professionals are critical to affect patient breastfeeding outcomes.

Recent Insights into Pregnancy and Lactation-Associated Osteoporosis (PLO).

During pregnancy and lactation, female physiology adapts to fulfill the fetal and neonatal calcium and phosphorus requirements. The physiological changes that take place during these periods do not affect maternal skeleton resistance to fracture in most of the cases. However, there is a small percentage of women that do experience fragility fractures during these times of life. Pregnancy and lactation-associated osteoporosis (PLO) is an infrequent condition defined by the occurrence of non-traumatic fractures - most frequently vertebral - during the third trimester of gestation and/or the first months of postpartum. Its physiopathology has not yet been completely elucidated. Several authors have reported that risk factors for secondary osteoporosis might be present in up to 80% of the cases of PLO patients. According to recent studies, genetic factors might also play a relevant role in PLO. Given its rarity, the available literature on this condition is limited. Most of the published data consist on case reports and case series articles. There are not any randomized controlled trials regarding this disorder. Although there is consensus about discontinuation of lactation and calcium and vitamin D supplementation as the first steps in the treatment of these patients, there is still controversy regarding the long-term and/or pharmacological management of this condition. Recent data on the use of teriparatide in this population looks promising. In this review, we aimed to revise and summarize current knowledge about the physiopathology and management of PLO.

Relationship focused mother-infant groups: Preliminary evaluation of improvements in maternal mental health, parenting confidence, and parental reflective functioning.

We report on two preliminary evaluations of a group intervention, targeting vulnerable infants and their mothers within the first 6-months postpartum. The Mother-Baby Nurture® program aims to strengthen the developing infant-mother attachment relationship by increasing maternal mentalizing. These studies were undertaken with pre-post evaluations with the mothers of infants under 10-months of age. The mother-infant dyads participated in ten 2-h group sessions. Study one (N=69 dyads) included self-reported maternal depression, anxiety, and parenting confidence. In study two (N=27 dyads), parenting stress and reflective functioning were measured by self-report, and reflective functioning coded on the 5 min speech sample (completed by N=22). Results from study one confirmed a decrease in depression (p<.001, d=.79) and anxiety (p<.001, d=.72) symptoms, and an increase in mothers' scores for parenting confidence (p<.001, d=-.98). Results from Study Two demonstrated a significant decrease in parenting stress (p<.001, d=.94) and significant improvement in measures of self-report reflective functioning (p=.007, .024; d=.56, .61). These findings are preliminary yet promising indications that this program could be effective in alleviating parenting stress, depression, and anxiety, and improving mother's reflective functioning and parenting confidence. Further research is needed, with a control group and long-term follow-up assessments.

Effect of 2-week postpartum check-ups on screening positive for postpartum depression: a population-based cohort study using instrumental variable estimation in Japan.

Postpartum depression is experienced by approximately 10% of women and affects the health and development of their children. Although it is recommended that all mothers have the opportunity for early detection and intervention for postpartum depression, it is unclear whether early postpartum check-ups help to reduce postpartum depression. The aim of this study was to assess the effect of 2-week postpartum check-ups on screening positive for postpartum depression in Japan. This was a population-based cohort study that used the administrative database of Tsuyama, Japan. Participants were women who received postpartum home visits from a public health nurse in Tsuyama during the fiscal years 2017-2019. Data were obtained on participant's attendance at a 2-week postpartum check-up and their responses on the Edinburgh Postpartum Depression Scale. Owing to the initiation of a publicly funded postpartum check-up programme, participants were pseudo-randomly assigned to receive/not receive a 2-week postpartum check-up. We conducted instrumental variable estimation to assess the causal effects of the check-up on screening positive for postpartum depression. The characteristics of the 1,382 participants did not differ by fiscal year of childbirth. We found a 6.7% (95% confidence interval 2.2-11.2) reduction in the prevalence of screening positive for postpartum depression as an effect of 2-week postpartum check-ups among women received 1-month postpartum home visits. The results suggest that 2-week postpartum check-ups are effective in reducing the prevalence of screening positive for postpartum depression among 1-month postpartum women. Despite some limitations, early postpartum care could reduce postpartum depression.

Infant colic and abdominal pain; associations with infant multimorbidity and maternal perceived stress up to 3 months postpartum-A cross-sectional/cohort study in the PreventADALL study.

The primary aim was to explore whether infants with pain symptoms (colic, abdominal pain and visit to healthcare provider with pain or other discomforts) had increased multimorbidity (common infections, eczema and food sensitivity) compared with infants without these conditions. Secondarily, we aimed to determine whether infant pain symptoms were associated with maternal perceived stress in pregnancy and 3 months postpartum. Infant colic and abdominal pain are common concerns in early infancy. Nevertheless, to our knowledge, little research exists on the relationship between infant pain and common infant infections, eczema and food sensitization as comorbidities, and the impact of infant pain on the development of maternal perceived stress from pregnancy to infancy is inconsistent. This study was cross-sectional and partly prospective. The sample consisted of mother-infant pairs (N = 1852); information regarding infant pain and multimorbidity was collected from the 3-month questionnaire and postpartum visits in the PreventADALL prospective cohort study. Chi-square tests and regression analyses were conducted. The STROBE checklist was followed. Our results showed a statistically significant higher proportion of respiratory and other infections in infants with pain symptoms. The odds of infant pain were higher for infants with multimorbidity compared to those with no comorbidity. Mothers of infants with colic and of infants visiting healthcare with pain and other discomforts reported statistically significant higher perceived stress by 3 months compared with mothers of infants with no reported pain. Our results indicate an association between infant pain symptoms and the presence of infections. Mothers of infants with colic and visiting healthcare had higher perceived stress compared to the no pain group. Our study indicates that infant pain is associated with infant multimorbidity and maternal perceived stress, which may be useful when planning diagnostic, treatment and coping strategies in infant and family care. The PreventADALL is a collaborative study with governmental and patient organisation representation. Selected infants with parents were also contributing during calibrating courses on eczema assessment for the data collectors. The study was approved by the Regional Committee in Norway (2014/518) and Sweden (2014/2242-31/4) and registered at clinicaltrial.gov (NCT02449850).

Associations of prenatal and childhood Pb exposure with allostatic load in adolescence: Findings from the ELEMENT cohort study

The biological pathways which link lead (Pb) and long-term outcomes are unclear, though rodent models and a few human studies suggest Pb may alter the body's stress response systems, which over time, can elicit dysregulated stress responses with cumulative impacts. This study examined associations between prenatal and early childhood Pb exposure and adolescent allostatic load, an index of an individual's body burden of stress in multiple biological systems, and further examined sex-based associations. Among 391 (51% male) participants in the ELEMENT birth cohort, we related trimester-specific maternal blood Pb, 1-month postpartum maternal tibia and patella Pb, and child blood Pb at 12–24 months to an allostatic load index in adolescence comprised of biomarkers of cardiovascular, metabolic, neuroendocrine, and immune function. The results were overall mixed, with prenatal exposure, particularly maternal bone Pb, being positively associated with allostatic load, and early childhood Pb showing mixed results for males and females. In adjusted Poisson regression models, 1 mcg/g increase in tibia Pb was associated with a 1% change in expected allostatic load (IRR = 1.01; 95%CI 0.99, 1.02). We found a significant Pb × sex interaction (IRR = 1.05; 95%CI 1.01, 1.10); where males saw an increasing percent change in allostatic load as 12 month Pb levels increased compared to females who saw a decreasing allostatic load. Further examination of allostatic load will facilitate the determination of potential mechanistic pathways between developmental toxicant exposures and later-in-life cardiometabolic outcomes.

Psychometric Properties and Factorial Structure of Postpartum-Specific Anxiety Scale (PSAS) Within Arabic Language in a Palestinian Context.

The Postpartum-Specific Anxiety Scale (PSAS) is an international measure designed to evaluate anxiety experienced by mothers in the postpartum period from one day to six months; the scale was translated into Arabic and validated within Palestinian context to test postpartum anxiety among Palestinian women. The current study aimed to test the psychometric properties and the factorial structure within the Arabic language in a Palestinian context using confirmatory factor analysis (CFA). The sample of this study consisted of 475 Palestinian women recruited from health centers in the West Banks of Palestine using a convenience sample. 61% were of ages 20-30 years and 39% percent ages 31-40 years. The PSAS showed good validity and reliability indicators in assessing postpartum anxiety within Palestinian context. Results of CFA showed a stable construct of a four-factor structure in assessing postpartum anxiety among Palestinian mothers: (1) competence and attachment anxieties, (2) infant safety and welfare anxieties, (3) practical baby care anxieties and (4) psychosocial adjustment to motherhood, which is consisting with the original four-factor structure of the scale. The PSAS showed good validity indicators within Palestinian context. Therefore, it is recommended to conduct similar studies with clinical and non-clinical groups in the Palestinian society. The PSAS can be a useful measure to assess anxiety levels among women during the postpartum months; which will enable mental health providers to provide psychological interventions for mothers whose anxiety levels are high.

A systematic literature review to examine the considerations around pregnancy in women of child-bearing age with myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) or aquaporin 4 neuromyelitis optica spectrum disorder (AQP4+ NMOSD).

Aquaporin-4 antibody positive (AQP4+) neuromyelitis optica spectrum disorder (NMOSD) and myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) are rare autoimmune diseases with overlapping phenotypes. Understanding their clinical manifestation prior to, during and after pregnancy may influence the management of women of child-bearing age (WOCBA) with these diseases. This systematic review identified relevant MEDLINE-indexed publications dated between 01 January 2011 and 01 November 2021, and congress materials from key conferences between 01 January 2019 and 01 November 2021. These were manually assessed for relevance to AQP4+ NMOSD and/or MOGAD in WOCBA, with selected data extracted and considered. In total, 107 articles were retrieved and reviewed for relevancy, including 65 clinical studies. Limited evidence was found regarding a conclusive impact of either disease on female fertility, sexual function or menarche, and impact on maternal outcomes requires further investigation in both conditions to establish risk for pre-eclampsia, gestational diabetes and other complications relative to the general population. Collated data for pregnancy outcomes show clear risks in AQP4+ NMOSD to healthy delivery and a rise in annualised relapse rate postpartum that may require adaptation of treatment regimens. Disease activity appears to be attenuated during pregnancy in MOGAD patients with an increased risk of relapse during the postpartum months, but strong conclusions cannot be made due to a paucity of available data. This review brings together the literature on AQP4+ NMOSD and MOGAD in WOCBA. The potential impact of pregnancy and the postpartum period on disease activity suggest a proactive management strategy early on may improve maternal and infant outcomes, but more clinical data are needed, particularly for MOGAD.

Human milk EV-miRNAs: a novel biomarker for air pollution exposure during pregnancy

Exposure to ambient and near-roadway air pollution during pregnancy has been linked with several adverse health outcomes for pregnant women and their babies. Emerging research indicates that microRNA (miRNA) expression can be altered by exposure to air pollutants in a variety of tissues. Additionally, miRNAs from breast tissue and circulating miRNAs have previously been proposed as a biomarker for breast cancer diagnosis and prognosis. Therefore, this study sought to evaluate the associations between pregnancy exposures to ambient (PM10, PM2.5, NO2, O3) and near-roadway air pollution (total NO x , freeway NO x , non-freeway NO x ) with breast milk extracellular vesicle miRNA (EV-miRNA), measured at 1-month postpartum, in a cohort of 108 Latina women living in Southern California. We found that PM10 exposure during pregnancy was positively associated with hsa-miR-200c-3p, hsa-miR-200b-3p, and hsa-let-7c-5p, and was negatively associated with hsa-miR-378d. We also found that pregnancy PM2.5 exposure was positively associated with hsa-miR-200c-3p and hsa-miR-200b-3p. First and second trimester exposure to PM10 and PM2.5 was associated with several EV-miRNAs with putative messenger RNA targets related to cancer. This study provides preliminary evidence that air pollution exposure during pregnancy is associated with human milk EV-miRNA expression.

Helping first-time mothers establish and maintain breastfeeding: Access to someone who can provide breastfeeding advice is an important factor.

First-time mothers often need help with breastfeeding and may feel isolated and uncertain about whom they can turn to for help with breastfeeding challenges. Exploration of whether access to breastfeeding advice helps new mothers initiate and continue breastfeeding is necessary. This study investigated the associations between ease of access to breastfeeding advice for first-time mothers and breastfeeding initiation and duration. This was a prospective, longitudinal cohort study of 3,006 women who delivered their first child in Pennsylvania, USA; with prenatal and postpartum interviews. At 1-month postpartum participants reported the extent to which they had access to "Someone to give you advice about breastfeeding if you needed it", via a 5-point scale ranging from "none of the time" to "all of the time". There were 132 women (4.4%) who reported that they had access to someone to give them advice about breastfeeding "none of the time"; 697 (23.3%) reported access "a little of the time" or "some of the time"; and 2,167 (72.3%) reported access "most of the time" or "all of the time". While the majority of the new mothers were breastfeeding at 1-month postpartum (72.5%), less than half were still breastfeeding at 6-months postpartum (44.5%). The higher the level of access to advice about breastfeeding the more likely women were to establish breastfeeding by 1-month postpartum and to still be breastfeeding at 6-months. For first-time mothers, ease of access to someone who can give them advice about breastfeeding facilitates breastfeeding establishment and continuation.

Association between maternal eating and young child feeding in a community sample

BackgroundEarly childhood is a pivotal period for the development of healthy eating practices. One way to promote child health is to identify early modifiable factors that affect child eating and weight. Given the intergenerational transmission of eating behaviors, this study examined how mothers’ eating behaviors were associated with child feeding practices, and whether child weight-for-length (z-WFL) moderated this relation, in a community sample.MethodsParticipants were 72 mother–child dyads. Maternal eating behaviors—emotional, external and restrained—were assessed 9-months postpartum, using the Dutch Eating Behavior Questionnaire. Child feeding—restrictive, pressure, and concern about overeating/overweight or undereating/underweight—was measured using the Infant Feeding Questionnaire, and child z-WFL were assessed 18-months postpartum. Linear regressions were used to test the main effect of maternal eating and the interaction effect of maternal eating and child z-WFL, on child feeding practices.ResultsMaternal restrained eating was associated with child pressure feeding, and contrarily with concerns about overeating/overweight. However, a significant interaction between child z-WFL and both maternal emotional and external eating were found with regard to concern about child undereating/underweight. Paradoxically, among children who weighed more, greater maternal emotional and greater external eating were associated with greater concern about child undereating/underweight.ConclusionsIn this community sample, mothers were more likely to report contradictory feeding practices and concerns, suggesting complicated relations among a mother’s own eating behavior, her child’s weight, and her perceptions of child eating and weight. This may indicate a need for better communication and support of infant feeding practices.Trial registrationData was collected as part of two grants (MAMAS Grant ID: HL097973-01; SEED Grant ID: HL116511-02) conducted at the University of California, San Francisco (UCSF). All subjects gave their informed consent for inclusion before they participated in the study. The study was conducted in accordance with the Declaration of Helsinki, and the protocol was approved by institutional review board at UCSF.

66-LB: Poor Sleep Is Correlated with Higher Parenting Stress in Women Who Have Had Gestational Diabetes

Background: Theoretically, women who have had GDM are likely to have increased stress levels following pregnancy related to parental stress exacerbated by concerns about personal health (e.g., development of T2DM). Such stress may negatively impact sleep, however, the relationship between parenting stress and sleep in women who have had GDM has not been well investigated. Therefore, the purpose of the study was to explore the correlations between sleep and parenting stress in people who have had GDM. Methods: Twenty-six woman (ages: 34.22 ± 3.51 years; ethnicity: African American [38.46%], Hispanic [30.77%], Caucasian [19.23%], and Asian [11.54%]; A1C: 5.78 ± .98 %; BMI: 36.28 ± 10.70; age of child from GDM pregnancy: 6.07 ± 3.95 months; number of children: range1-6; months of postpartum: 6.06 ± 3.96) who had GDM on the previous pregnancy completed self-reported questionnaires. These included Parenting Stress Index (PSI-4, SF), PROMIS Global Health-Physical (v.1.2;2a), PROMIS Fatigue (v.1.0;8a), PROMIS Sleep Disturbance (v.1.0;8b), and PROMIS Sleep-Related Impairment (v.1.0;8a). The Spearman’s correlation was used to analyze data using STATA 17.0. Results: The mean total score on the Parenting Stress Index was positively correlated with PROMIS Fatigue (Spearman’s r = 0.61, p &amp;lt; .01); PROMIS Sleep Disturbance (r = 0.61, p &amp;lt; .001); and PROMIS Sleep-Related Impairment (r= 0.57, p &amp;lt; .001). On the other hand, the mean total score on the Parenting Stress Index was negatively correlated with PROMIS Global Health-Physical (r = -0.58, p &amp;lt; .01), and was not correlated with A1C and BMI. Conclusion: In this glucose intolerant group of women with previous GDM, parenting stress was correlated with fatigue alone with sleep disturbances and impairments. In addition, parenting stress was negatively correlated with individuals’ assessment of their health. Finding suggested that it is necessary to explore the associations between parenting stress, sleep, and glucose metabolism in women who have had GDM. Disclosure M. Park: None. Y. Song: None. M.

An intensive longitudinal investigation of maternal and infant touching patterns across context and throughout the first 9-months of life.

Touch is a central component of mothers' and infants' everyday interactions and the formation of a healthy mother-infant relationship. Twelve mothers and their full-term infants from the Midwest, USA participated in the present study, which examined the quality and quantity of their touching behaviors longitudinally at 1-, 3-, 5-, 7-, and 9-months postpartum and within two normative interaction contexts (face-to-face, floor play). Findings revealed that mothers' and infants' individual touch patterns, varied according to context, infant age (time), and the specific type of touch examined. At 1-month postpartum, dyads coordinated their touch via behavioral matching and were especially reliant on rudimentary types of touch with soothing and regulatory properties (static/motionless touch, stroking). As infants aged to 9-months, dyads transitioned to a more complex form of tactile synchrony characterized by the parallel use of complementary types of touch (grasp, poke, pull). This evolution of tactile synchrony may reflect infants' growing behavioral repertoire and increased capacity to use more refined forms of touch. To our knowledge, this study was the first of its kind, uniquely contributing to the scant knowledge about the development of mother-infant touch and synchrony and offering direct implications for early care practices and infant health and well-being.

Persistent symptoms of maternal post-traumatic stress following childbirth across the first months postpartum: Associations with perturbations in maternal behavior and infant avoidance of social gaze toward mother.

Recent literature identifies childbirth as a potentially traumatic event, following which mothers may develop symptoms of Post-Traumatic-Stress-Following-Childbirth (PTS-FC). The current study examines whether stable symptoms of PTS-FC during the early postpartum period may impose risk for perturbations in maternal behavior and infant social-engagement with mother, controlling for comorbid postpartum internalizing symptoms. Mother-infant dyads (N=192) were recruited from the general population, during the third trimester of pregnancy. 49.5% of the mothers were primipara, and 48.4% of the infants were girls. Maternal PTS-FC was assessed at 3-day, 1-month and 4-month postpartum, via self-report and clinician-administered interview. Latent Profile Analysis generated two profiles of symptomology: "Stable-High-PTS-FC" (17.0%), and "Stable-Low-PTS-FC" (83%). Membership in the "Stable-High-PTS-FC" profile associated with perturbed maternal sensitivity, which was in turn significantly associated with infant avoidance of social gaze toward mother (Indirect effect β=-0.15). Results suggest the need for early screening and inform the planning of early preventive interventions.
